The works which I have studied on this subject are, 1.

_Florentiner Studien_, von P.
Scheffer-Boichorst, Leipzig, Hirzel, 1874.2._Dino Compagni vendicato dalla Calunnia di Scrittore della Cronica_, di Pietro Fanfani, Milano, Carrara, 1875.3._Die Chronik des Dino Compagni, Versuch einer Rettung_, von Dr.Carl Hegel, Leipzig, Hirzel, 1875.
4.

_Die Chronik des Dino Compagni, Kritik der Hegelschen Schrift_, von P.Scheffer-Boichorst, Leipzig, Hirzel, 1875.5.The note appended to Gino Capponi's _Storia della Repubblica di Firenze_.

6.
_Dino Compagni e la sua Chronica_, per Isidoro del Lungo, Firenze, Le Mornier.

Unluckily, the last-named work, though it consists already of two bulky volumes in large 8vo, is not yet complete; and the part which will treat of the question of authorship and MS.
authority has not appeared.
The year 1300, which Dante chose for the date of his descent with Virgil to the nether world, and which marked the beginning of Villani's 'Chronicle,' is also mentioned by Dino Compagni in the first sentence of the preface to his work.
